WILLIAM THOMAS BAUSMITH. 0E ABERDEEN, MARYLAND.

Letters Patent No. 112,886, dated March 21, 1871.

IMPROVEMENT IN SASH-HOLD ERS.

The Schedule referred to in these Letters Pflcnt and making part of the same.

erence marked thereon making a part of this specifi-v cation.

The nature of my invention consists in securing the screw in a sash-lock, provided with aflexible cam, by means of a face-plate, which is screwed to the metal boxing, all asmore fully hereinafter set forth.

In order to enable others skilled in the art to which my. invention appertains to make-and use the same, I .will now proceed to describe its construction and operation, referring to the annexed drawing, in Which Figure 1 is a longitudinal vertical section of my sash-lock and Figure 2 is a front view of the same with the outer plate removed.

- A represents a circular plate of suitable dimensions,

provided with a handle, B, and on one side with an annular flange, O, forming, as it were, a round box.

The flange 0 does not project immediately from the edge of the plate, but far enough in to leave a small shoulder or offset, a, around the entire flange, as shown in fig. 1.

Around this flange or box C is placed a rubber ring,

D, of suitable thickness.

In the box 0, extending upward from the plate A,

is a projection, b, extending from the center to one side, as seen in fig. 2.

Through this projection, away from the center, passes a screw, E, which pivots the entire device to the window-frame.

The box 0 is then covered by an ornamental plate,

G, fastened by a central screw, cl, which face-plate thus covers and hides from view the head of the.

screw E.

This device being pivoted to thewindow-frame oil" from the center, forms a rubber-covered cam for holdingaud locking the sash, as will be readily understood.

I am aware that cams, with or without rubber c ov ering, have been used for sash-locks, and I do not claim such as my invention, my invention consisting principally in securing, by means ofa plate, the screw which fastens the cam t0 the window-frame, said plate being itself secured by a central screw, forming a part of the ornament on the plate.

What I claim is- In combination with the plate A, handleB, flange 0, rubber ring D, and screw E, the face-plateG and central screw d, substantially for the purposes herein set forth.

In testimony that. I claim the foregoing I have hereunto set my hand this 4th day of January, 1870.
